JOHN WASHINGTON YEWELL, OF BALTIMORE, MARYLAND.

SHIPS WINDLASS.

SPECIFICATION forming part of Letters Patent No. 434,054, dated August 12, 1890.

Application filed November 16, 1889- Serial No. 330,547. (No model.)

To all whom it may concern:

Be it known that I, JOHN WVASHINGTON YEWELL, of the city of Baltimore, and State of Maryland, have invented certain Improveinent-sin Ships Windlasses, of which the following is a specification.

The object of this invention is to prevent unequal wear of the ratchet-teeth and the pawl of a Windlass, caused by the free end of the pawl moving outwardly from the flange of the head, or toward the edge of the ratchet-disk.

The said invention consists in providing the pawl with an extension beyond its hub or part thereof through which the pivotal bolt passes, the said extension bearing against the side of the flange of the head, as will hereinafter fully appear.

In the drawings forming a part hereof, Figure 1 is an exterior front View of the ll1'l proved Windlass, and .Fig. 2 an end View of the same. Fig. 3 is a cross-section of- Fig. 2, taken on the dotted line w as. Fig. 4 illustrates a modification in the construction of the invention, as hereinafter described.

Similar letters of reference indicate similar parts in all the figures.

Referring to Figs. 1, 2, and 3, A is the shaft of the Windlass, confined in boxes a, secured to the bits B.

O O are the Windlass-heads, which are either secured to or rest loosely on the shaft A. The heads are each provided with two toothed disks 1) and a, the former situated at the inner and the latter at the outer end of the head.

The pawls which engage with the ratchetdisks 1) and c are respectively denoted by d and F.

G G are sockets into which the handspikes for turning the heads are inserted, and to which the pawls F are pivoted. The pawls F have each an extension or tail f, leading froin the hub g, and the inner surface of this tail bears against the face of the head and prevents the pawl assuming an angular position with reference to it, as will be readily understood.

I do not limit myself to the construction of the tail-piece of the pawl F, which is-shown, as it may extend nearly or quite around the ratchet-disk and be united to the free end of the pawl, as shown in Fig. 4.
